role of regulatory intervention and the polycentric
governance of socioeconomic systems.
There is a growing consensus that the failure of
mainstream economics to predict the collapse of
2008 and the subsequent failures in policy responses
have prompted the need for new economic thinking.
Such a failure to provide understanding and solid
theoretical explanations for real-world phenomena
necessitates a re-examination of its philosophical
tenets.
Classical economic theory, with its focus on
equilibrium models, gives very little attention to
instabilities and out-of-equilibrium dynamics.
According to the Chicago School of Economics, an
out-of-equilibrium "inefficient" market is
theoretically impossible, and bubbles are neither
predictable nor detectable. The paradigm of classical
economic theory relies on independent
(representative) agents, competitive markets,
equilibrium models, additively aggregated variables,
and predictability. It fails to recognize the part/whole
relationships and nonlinearity that arise from
interconnectivity and complexity, leading to a
growing discrepancy with the reality it attempts to
model.
A more accurate approach to modeling economic
reality involves system thinking, considering
interconnected agents in a complex system of semi-
autonomous levels, ranging from sole proprietorships
and partnerships (SME) to small, medium, and large
corporations. Order emerges, and it is not
predetermined, featuring unpredictable, nonlinear,
and path-dependent dynamics. At each level of the
hierarchical structure, self-similar units possess
similar speed and singularity thresholds sustaining
dynamic equilibrium. Cross-scale interactions
(feedback control mechanisms) preserve the integrity
of the system.
Scientific progress in financial economics is hindered
by an over-reliance on econometric models as tools
of the dominant methodology. A shift analogous to
the transition from Newtonian to Einsteinian
gravitational theory is needed, recognizing the role of
philosophical interpretation in this transformation.
The reluctance of financial economists to engage in
philosophy of science discussions may stem from the
need to preserve implicit methodological standards,
despite explicit methodological arguments
supporting alternative approaches (e.g., behavioral
economics).
Arguments against prevailing economic
methodology reveal the necessity for substantial
modification of traditional methodological
conceptions and motivate alternative choices of
philosophical positions. Based on the dialectical law
of the passage of quantitative changes into qualitative
changes, the equilibrium concept's methodological
merits may be critiqued. As the theory does not
address out-of-equilibrium economics, it fails to
provide tools for the detection of instabilities. The
equilibrium concept, through the technique of
independent variables aggregation, eliminates
important aspects of interdependence and feedback
control, obscuring interesting parts of the theory that
might bear on disruptive change and resilience.
Quantifying complex systems aims to explain
emergent structures and self-organization. The
hierarchical structure and self-similarity of the
system create the potential for synchronization of
dynamics, leading to the famous "butterfly effect"
that may result in a collapse. Monitoring coupling
levels among subsystems and the process of
synchronization provides indications about the
stability of the system. Statistical complexity
measures, such as those proposed by Rosso et al.
(2010), characterize the system with its level of
disorder and its distance from equilibrium. These
measures offer quantitative methods for empirical
testing of instability indicators.
Recent work on understanding the potential for
disruptive change in complex public sector systems
argues for heterogeneity, adaptability, and learning
among agents. These agents, whether organizations
or institutions, interact at different levels, constituting
larger sectors such as industries or public sector
agglomerations. Managing the ability of sectors to
co-evolve is crucial for achieving the declared
outcomes of the larger system. Co-evolution in such
a complex system occurs both between agents
themselves and between agents and the external
environment. Recognizing and accounting for
competition for resources are essential, providing
adaptive tension that drives the system forward.
Research on complex adaptive systems (CAS)
suggests that they operate most effectively within a
range defined by two critical values based on the
amount of adaptive tension applied to the system.
Steering a CAS involves providing incentives to
move the system past the first critical value,
empowering self-organizational capabilities for
adaptation and innovation. However, it's crucial to be
aware that 'too much of a good thing' is also
dangerous, and damping mechanisms should be part
of the toolbox. McKelvey (2002) emphasizes the
relevance of damping mechanisms for policy
managers, considering the balance between
suppressing positive dynamics too quickly and not
suppressing negative dynamics quickly enough.
While the complexity toolbox can help guide systems
to adaptive novelty, the assumptions underlying
